b. How to Begin Troubleshooting.
(1) Determine the symptom or condition that indicates a problem or failure. Troubleshooting is divided into
symptoms peculiar to a vehicle system or component, for example: pneumatic system or engine. Refer
to the Troubleshooting Fault Index (Table 2-1).
(2) Go to the referenced page to begin troubleshooting. Open the manual flat so both the left-hand and
right-hand pages are displayed before you. The information on both pages is important to resolve the
problem or failure. However, the experienced technician can follow the left-hand page instructions and
refer to the right-hand page when necessary.
(3) Follow the Diagnostic Procedure. Answer question No. 1 on the left-hand page and follow the YES or
NO path to either the remedy or the next question. If necessary, look on the right-hand page for test
instructions and illustrations.
(4) Observe warnings, cautions, and notes. The formatting and symbols used in this manual for warnings,
cautions, and notes are as follows:
This is the symbol for a warning statement. If you see the word WARNING above a question on
the left-hand page, look on the right-hand page for the text of the message. WARNINGs
describe a situation which could cause serious injury or death to personnel.
This is the symbol for a caution statement. If you see the word CAUTION above a question on
the left-hand page, look on the right-hand page for the text of the message. CAUTIONs describe
a situation which could cause damage to equipment.
This is a symbol for a note. Notes are located directly above the test to which they refer. NOTEs
provide additional information for performing a test.
c. Confidence Tests. Before performing any STE/ICE-R test, a confidence test must be run to ensure proper
operation of the STE/ICE-R. In addition, a confidence test must be performed after each use to ensure
the STE/ICE-R is performing properly. Refer to TM 9-4910-571-12&P.
d. Verifying Repair. When troubleshooting, there is an additional step that must be performed after taking
any corrective action. This step will show that the malfunction has been corrected, or that additional
troubleshooting is required, example follows:
On malfunction d1. Wheel wobbles or shimmies, the question is asked "Is the steering knuckle free from
damage?". If the question was answered NO, the damaged steering knuckle was replaced. After replacing the
damaged steering knuckle, the vehicle must be checked to determine if the original malfunction is still
present. If corrected, troubleshooting is completed. If malfunction is still present, continue troubleshooting.
